Review on Schioppa GLAP 210 GEL Polyurethane by David Lesperance

Good roller - looks good and rolls well. The locking mechanism also seems to work very well. I used them to put under a moving platform I had built. They roll well on carpets and hard floors. On soft carpet they sink a little and roll harder, but that's not surprising. I wouldn't call it a problem. I used 2 casters with locks and 2 casters without locks. The mounting platform was easy to screw on. I like that they look good, have a low profile and are decently priced.
